WATER-HEATER.

Specification of Letters Patent.

Patented Dec. 30,1919.

Application filed April 11, 1918. Serial No. 227,974.

To all whom it may concern:

Be it known that I, GEORGE W. WVANNER, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Water-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to water heating means for gas or other ranges.

One object of my invention is to provide a water heating means which shall be suitable for use with either coal, Wood, electric or gas ranges.

Another object of my invention is to provide a water heating means which shall heat water by means of the heat which is now wasted. v

Another object of my invention is to provide a water heating means which shall be simple, cheap, effective and safe in use.

Another object of my invention is to provide a Water heating means which can be readily adapted to coal and gas ranges that are in use, or made a part of the structure of new coal or gas ranges at very small additional expense.-

Another object of my invention is to provide a water heating means which can be readily cleaned out in case the water chamber should become clogged with mud or should scale form thereon, thus providing at all times for a maximum efliciency.

In carrying out my invention I make use of the instrumentalities illustrated in the accompanying drawings, in which- Figure'l is a plan view of a gasrange equipped with my new water heating device.

Fig. 2 is an enlarged section along the line 22 of Fig. 1 looking in the direction of the arrows in said figure.

Fig. 8 is a View similar to Fig. l but with the top plate of my improved heater broken away and all parts of the range omitted.

Fig. 4 is a side view of the fusible plug I employ to prevent an explosion should the chamber of my improved water heater become dry and the same become overheated.

In the drawings 10 represents the frame work of a gas range which is supported by the usual legs 11 and provided with the usual burners 12-121212 of any approved type and they are connected by the pipes l31313 13 With the cooks 14-14l1414; and the latter are connected with the gas manifold 15, which is connected with any suitable source of gas.

My improved heater consists of the casting 16 which is provided with a Hat top 17 a flat bottom 18, sides 19 and 20, back 21 and front 22.

Four cylindrical holes such as 23 extend through from the bottom 18 to near the top 17 where said holes are provided with the enlarged portion 24. Said enlarged portions 24: are provided for the reception of a lid or a cooking utensil.

The holes 28 are surrounded by the cylindrical metallic portions 25 which join up at the top and bottom with the top 17 and bottom 18 respectively. 7

Extending from the bottom 18 to the top 17 are any suitable number of stay pieces such as 26 which are intended to keep the top and bottom at the proper distance apart.

A baflie plate such as 27 also extends from the bottom 18 to the top 17 and said baille plate is curved around as at 28 for a purpose hereinafter explained. .Any suitable number of holes, closed by plugs such as 29, are provided in the side 20, back 21 and front 22 for a purpose hereinafter explained.

. The cold water supply pipe is represented by 30 and the hot water supply pipe by 31. These pipes are connected respectively by the goose necks 32 and 33 to the water chamber 34 formed between the top plate 17, the bottom plate 18, the sides 19 and 20, the back 21, the front 22 and surrounding the cylindrical ortions 25.

It is to e noted that the cold water goose neck 32 is threaded into a hole in the boss 35 which connects with the water chamber 34 on the concave side of the baflle plate 27, and that the hot water goose neck 33 is threaded into a hole in the boss 36 which connects with the water chamber 34on the convex side of the baffle plate 27.

Ribs such as 37 extend around any desired portion of the bottom 18 and a similar rib 38 also extends around said bottom and parallel to the rib 37 ,-the two ribs being a sufficient distance apart as to embrace the upperedge 39 of the frame 10 of the range. Any suitable number of tabs such as 40 are also provided on the bottom 18 and rivets such as -i1 passing through same and the upper edge 39 of the frame of the gas range serve to secure my improved heater in place thereon.

In order to prevent an explosion should chamber 3% of my improved heater become dry and the bottom 18 become overheated, I provide a fusible plug an, as shown in i, which consists of a metallic plug threaded as at 42, provided with a squar head $3 for the reception of a wrench and with a central tapering hole filled with a fusible metal =l-.l. This plug is screwed into the center of the bottom 18 as shown in the fi ures.

The top 1?, the bottom 18, the sides 19 and 20, the back 21, the front 22, cylinders 25, stay pieces 26, bal'lle plate 2?, the bosses 35 and 36, ribs 37 and 38, tabs -l-0 and rib d6 are all cast integrally.

The operation of my improved heater is as follows:

Cold water arriving by the cold water supply pipe 30 passes through the goose neck 32 into the chamber 3% on the concave side or' the battle plate 27, said water then pas es in the direction of the arrows in Sig. 3 around the cylindrical portions and leaves by the hot watergoose neck 33 and the hot water supply pipe 31.

The supply pipes and 31 are to be provided with valves in the usual manner and the goose necks 32 and 83 are provided to prevent the draining of the water chamber Should at any time, however, the water leave the chamber 3st and the gas be burnine', the fusible metal 4% will melt and run out of the plug 4:1; consequently, it the water should then pass into the chamber 3% while my improved heater is heated, the sudden generation of steam will not cause an explosion because the same will blow out be understood that the same heater can be applied on a coal, wood or electric stove and that the usual lids of the coal stove will be made to fit the recess portions 24.

Furthermore, when the device is used on coal stove, a hole such as :5 leading into the coal space of the coal stove is provided for the passage of the hot air and gases.

The hole is surrounded by a rib 46 for the reception or the stove pipe. It is evident that many variations may be made in my improved heater without departing from the spirit of my invention.

1 claim In a water heater, a back, a top and a bottom each provided with heating holes and pipe holes adjacent said back for the passage of waste heat therethrough, sides, a front, and walls surrounding said holes and extending between said bottom and top, the aforesaid parts forming a water chamber, in combination with a baffle plate extending from one of said sides in spaced relation partially around the wall surrounding a heating hole remote from said pipe holes and extending nearly to said front, a cold water connection to said water chamber adjacent theside of said ballle plate facing said GEORGE W. WANNER.
